Lancashire & Yorkshire 0-4-4 Locomotives in Great_Britain


Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 10290)

Data from "Locomotives for the Lancashire & Yorkshire Ry - Designed by Mr B Wright", The Locomotive Magazine, Vol VIII (7 March 1903), p. 164-165. See also [], last accessed 5 May 2009.

One of the components in short supply in 1878 on the L & Y was turntables, according to Steamindex observed that although Manchester was one of the leading rubber-manufacturing centers in England, the rubber springs fitted in this class were unsatisfactory. After the railway refitted the side springs in the locomotives with Timmins coil springs, the ride was "excellent".

Dubs supplied 10 (works 1150-1159) in 1878, Kitson & Company added 10 (works 2216-2225) in 1879, Neilson & Company (2370-2379), also in 1879, but fitted with smaller-capacity side tanks. Slightly heavier bogie tanks were added to the stud in 1885-1886 when Sharp, Stewart produced a batch of 40 engines (works 3299-3338).

Most of the class was withdrawn before World War One.
